@coolbreeze @Dutch-Mic Thanks for your input! I've ended up getting the M+ version, as it was basically the same price here as the M version.
I've just tried my first extraction. I've heated it using single jet lighter right at the dots until I've heard a click. I've stopped heating right at the click, but I think I still combusted somehow. Herb was kinda black, almost ashy, taste wasn't good. I'll try heating the tip/bottom of the cap next time. Any ideas why could I have combusted?
EDIT: Tried another exctraction, now on the bottom of the cap. This extraction produced little vapor and didn't char the herb, it was light brown colored, nowhere near close combustion. Produced just little of vapor however, 3 heatings total (always waiting for the click signaling the cooldown). Clicked pretty quickly.
EDIT2: On first extraction (the combustion one), I've ground my herb to dust almost, it was very finely ground. Also there wasn't much of it. So my guess is that due to the very finely ground herb, there not being enough of it and heating bellow the cap, it clicked way too late.
On the first extraction, I just "tore" the nug into little pieces and there wasn't much of it. My guess there would be that cap clicked much sooner and it didn't heated the herb much, so there was little of vapor.
